DP83825IRMQT - 10/100 Ethernet PHY, 24-WQFN | Texas Instruments
Teilenummer: DP83825IRMQT ✓ AktivDP83825IRMQT Übersicht
An Ethernet PHY is the physical-layer component that converts logical data from a MAC into electrical signaling for a twisted-pair network. It belongs to the Ethernet transceiver hierarchy and implements the physical specifications of 10BASE-T and 100BASE-TX. The DP83825I family connects to CAT5e media through an external transformer, allowing industrial and embedded designs to use the same Ethernet PHY for both 10-Mbps and 100-Mbps links.
Key features include programmable energy-saving modes, including active sleep and deep sleep, along with Energy Efficient Ethernet and Wake-on-LAN support. The integrated MDI and MAC termination resistors can reduce external discrete-component requirements, while the 50-MHz clock output provides a convenient reference for compatible system circuitry. Its 3 mm by 3 mm WQFN-24 package supports compact industrial designs without requiring a larger connector-side layout.
The DP83825I uses integrated PMD sublayers to support 10BASE-T and 100BASE-TX protocols. The PHY interfaces directly with twisted-pair media through an external transformer, and the verified manufacturer description specifies cable reach of up to 150 meters over CAT5e. Because this is a physical-layer device rather than a complete network interface controller, the host system must provide the compatible MAC and required software or firmware support for Ethernet operation.
Typical uses include industrial control equipment, embedded Ethernet gateways, compact network terminals, factory automation interfaces, and low-power network-connected sensors. Its small package is particularly useful when connector placement and board area are constrained. In designs with energy-saving requirements, the available sleep modes can reduce activity when link or traffic conditions permit, although the host controller must implement the corresponding operating policy.
Designers should follow the manufacturer’s recommended transformer, termination, layout, and decoupling network rather than treating the PHY as a generic Ethernet jack controller. The 3 mm by 3 mm WQFN package requires careful PCB layout and adequate thermal relief around its exposed pad. Magnetic-component selection, center-tap capacitors, and copper-track geometry materially affect return loss, insertion loss, and radiated emissions.
This page consolidates the verified manufacturer specifications, distributor pricing, package details, and practical replacement guidance for DP83825IRMQT. It also distinguishes exact electrical alternatives from broader functional equivalents so engineers can make a defensible PCB-level replacement decision.

Industrial Control Gateways
The DP83825IRMQT fits industrial control gateways that need a 10/100-Mbps Ethernet link in a compact board area. Its 3 mm by 3 mm 24-WQFN package leaves more routing space around the connector and magnetics, while operation from -40 C to +85 C supports industrial-temperature equipment. The PHY reaches up to 150 meters over CAT5e and provides a 50-MHz clock output for compatible host circuitry. Design the external transformer, center-tap network, and return path using the manufacturer reference layout to preserve insertion loss, return loss, and EMC performance.
Empfohlen
Compact Network Terminals
DP83825IRMQT is well suited to compact network terminals where every millimeter of PCB area affects enclosure design. Its 24-WQFN package measures only 3 mm by 3 mm, and the integrated MDI and MAC termination resistors can simplify the analog network section. The device supports 10BASE-T and 100BASE-TX operation, IEEE 802.3 protocols, and links up to 150 meters over CAT5e. Its less-than-127-mW power specification also supports fanless equipment, although system idle behavior should be coordinated with the PHY’s active-sleep and deep-sleep modes.
Empfohlen
Factory Automation Interfaces
The DP83825IRMQT can serve as the Ethernet physical layer in factory automation interfaces such as sensor hubs, remote I/O modules, and industrial gateways. Its industrial temperature range of -40 C to +85 C and low consumption below 127 mW suit embedded network equipment operating continuously near power and data connections. Programmable active sleep and deep sleep offer additional power-management options when traffic is intermittent. The completed module still needs a transformer optimized for the target Ethernet channel, a compliant magnetic isolation network, and careful high-speed return-path layout.
Empfohlen
Power-Constrained IoT Devices
DP83825IRMQT supports low-power network-connected IoT equipment that requires wired Ethernet rather than a wireless radio. The PHY combines 10/100-Mbps operation with less-than-127-mW power consumption and programmable energy-saving modes, allowing designers to balance link availability against standby consumption. Energy Efficient Ethernet and Wake-on-LAN provide additional ways to reduce activity or react to remote signaling. Software must correctly configure the PHY through its host MAC interface, and the PCB must preserve the manufacturer’s recommended magnetic and high-speed layout geometry.
Empfohlen
Embedded Ethernet Hubs
DP83825IRMQT can provide a wired network attachment for embedded hubs and controllers with limited connector-side space. The 10BASE-T and 100BASE-TX support allows one PHY design to accommodate both legacy 10-Mbps and fast Ethernet links, while the 50-MHz clock output provides a useful timing reference where required by the surrounding architecture. Because the DP83825I is a PHY rather than a complete MAC, designers must pair it with a compatible Ethernet MAC and validate the media interface against the selected transformer and channel requirements.
Empfohlen
Networked Measurement Equipment
DP83825IRMQT is appropriate for networked measurement equipment that needs reliable 10/100-Mbps Ethernet connectivity without a large transceiver package. The industrial -40 C to +85 C rating supports equipment deployed in controlled industrial environments, and the 150-meter CAT5e reach permits connection to a local network backbone. Energy Efficient Ethernet, Wake-on-LAN, active sleep, and deep sleep can assist with remote monitoring and reduced power use. Validate the complete return loss, insertion loss, radiated-emissions, and immunity performance because the external transformer and PCB layout are integral to the Ethernet channel.

Wichtigste Unterscheidungsmerkmale
- Extremely compact Ethernet PHY footprint (vs. DP83825IRMQR)
- Low system power envelope (vs. DP83825IRMQR)
- Reduced discrete-component burden (vs. DP83825IRMQR)
- Power-management and remote-wake support (vs. DP83825IRMQR)
Designhinweise
Use the manufacturer reference layout for the RMQ footprint and high-speed differential pairs. Keep the PHY-to-transformer path short, match the differential pair geometry, provide a continuous ground reference, and avoid stubs or test pads that interrupt the pair. The 3 mm by 3 mm WQFN package leaves little room for improvisation, so validate creepage, solder-mask spacing, and component placement with the official land pattern before release.
Place the PHY’s supply-decoupling network directly at the relevant package pins and keep high-current return paths away from sensitive clock and differential nodes. The verified family specification is less than 127 mW, but that figure does not include transformer or system losses. Enable and power-state sequencing must agree with the host MAC because deep-sleep transitions can alter link behavior if firmware does not maintain the intended operating state.
Ethernet channel performance depends on the selected transformer, center-tap network, termination arrangement, and PCB return path, not only on the PHY itself. Compare insertion loss and return loss across 10BASE-T and 100BASE-TX channels, and test radiated emissions with the completed enclosure and cable arrangement. Avoid changing the magnetic network without repeating channel measurements because small layout changes can materially affect common-mode noise and emissions.
Do not substitute a broadly similar Ethernet PHY solely because it also supports 10/100 Mbps. A valid drop-in choice must match the RMQ footprint, pin assignments, supply architecture, clock requirements, termination implementation, transformer network, and host-driver expectations. The verified cross-reference listings include functional devices without complete pin-compatibility evidence, so each proposed replacement requires a manufacturer pinout and reference-design review.
Compliance-Informationen
The supplied manufacturer and distributor excerpts establish industrial-grade operation from -40 C to +85 C but do not state RoHS, REACH, lead-free, halogen-free, or conflict-minerals status. These fields remain unknown rather than being inferred from the product category.
